During 2020, the rate of reported hepatitis A in the United States was 3.0 per 100,000 population, a 47% decrease in the rate reported during 2019. The 6 states with the highest number of reported hepatitis A cases during 2020 (Alabama, Florida, Georgia, Louisiana, North Carolina, and South Carolina) account for approximately half the national burden. These states were heavily affected by outbreaks of hepatitis A associated with person-to-person transmission. Of note, in 2020 no hepatitis A cases were reported by Alaska.
